gm ATTORN CY Patented Feb. 23, 1932 UNITED STATES ROBERT M. HYDE, 0F LAUREL, MISSISSIPPI; VESTA M. HYDE ADMINISTRATRIX OE PATENT OFFICE SAID ROBERT M. HYDE, DECEASED SANITARY CLOSET Application filed January 16, 193 1.

The present invention relates to improvements in toilets and the primary object of the invention is to provide a sanitary odorless dry toilet primarily intended for use with tank or pit closets.

A further object of the invention is to provide a sanitary dry closet embodying means automatically operable for preventing the emission of odors into the toilet room.

A further object of the invention is to provide a closet provided with trap plates operable by the seat to be automatically opened when a weight is brought upon the seat and automatically closed when the weight is removed A further object resides in the arrange' ment whereby the closet will be properly vented at all times, and the arrangement whereby the trap plates will be disposed in a substantially protected position within the bowl or hopper when in use.

Other objects and advantages of the present invention will be apparent from the following detailed description taken in connection with the accompan ing drawings forming a part of this speci cation and in which drawings:

Figure 1 is a top plan view of the sanitary closet and showing the seat in a lowered position.

Figure 2 is a section on the line 2-2 of Figure 1 but showing the seat in a raised position and the trap plates closed.

Figure 3 is a rear plan view of the closet with the seat closed.

Figure 4 is a vertical section on the line H of Figure 3.

In the drawings and wherein similar reference characters designate corresponding parts thruout the several views, the improved closet comprises a bowl or hopper A provided with the seat B, and G designates closure means operable by movement of the seat B for automatically opening and closing passage thru the bowl or hopper A. g

The bowl A is preferably though not essentially made of metal and embodies a rectan gular shaped base 5 including vertical front and rear walls 6 and 7 respectively and vertical side walls 8. Extended about the lower Serial No. 508,238.

edges of the base walls is an outturned flange 9 for resting upon a suitable floor 10 about the margins of an opening 11. Removably fitting upon the upper end of the base 5 is a cap orhead piece 12 includingan upright cylindrical body portion 13 provided at its lower end with a rest flange le for seating upon the upper edge of the base 5. This rest flange 14 is provided about itsma-rginal edges with a downturned retaining flange 15 which snug ly engages about the upper edges of the base walls 6, 7 and 8 to prevent side movement of the head piece and also form atight joint between the head piece and base to prevent escape ofodors at the joint. As will be seen the diameter of the cylindrical body portion 13 isless than the size of the base 5 so that the rest flange 14 forms an inwardly extending shoulder along theupper edge of each wall of the base. 1

The seat B is of ordinary circular shape and is hingedly connected at its rear portion to the rearside of the cylindrical body portion 13. Secured to the under side of the seat B is a hinge member 16 which is pivotally connected to a bracket 1'7 carried bythe body portion 13. The hinge member 16 is provided with a rearwardly extending arm 18 which extends rearwardly of the pivotal axis of the seat and has attached to its rear end, the upperend of a coil spring 19. The lower end of thespring 19 is attached in any suitable manner to the base flange 9 and this spring serves to normally raise the seat 13 to a vertical position from above the bowl as shown in Figure 2.

Referring now to the closure means C for opening and closing passage thru the bowl A upon movement of the seat 13, the same in cludes a co-acting pair of swinging trap plates 2020 of rectangular shape and each having a tubular rolled edge 21. These plates 20 which are preferably of sheet metal, are of a length from front to back, greater than thediameter of the cylindrical body portion 13 and of a width slightly greater than one half the width of the base5 whereby the free edges of the plates will overlap when the plates are in their normal closed position as shown in Figure 2. Extended thruthe tubular edge 21 of each trap plate is ahinge pin 22 the ends of which extend beyond the ends of the plates and have pivotal mounting in the upper portions of the base walls 6 and 7 closely adj acent the base side walls 8. The retaining flange 15 may be provided with downwardly opening slots as shown in Figure 3. to accommodate the ends of the pins 22. The hinge pins 22 are fixed in the tubes 21 whereby upon rotation of the pins, the "trap plates will be moved therewith. The rear projecting-end of each hinge pin 22 is formed with a crank arm 23 provided at its end with an eye 24; in which are hingedly connected. the lower ends of links 25 which may be formed with eyes 26 for connection with the eyes 2d. EX- tended transversely thru the arm 18 rearwardly of its pivot, is a rod 28 having an eye 29 formed: at each end thereof for connection in the eyes 30 formed at the upper end of each. link25.

WVhen the seat B is in its normal raised position as in Figure 2, the crank arms 23 are inclined outwardly and. downwardly at an angle of about from the side walls of the base, and when the seat is lowered upon the upper edge of thecylindrical body portion 13,

the. crank. arms are swung, upwardly thru' substantially. 90 so as to extend outwardly and upwardly from the base side walls as in Figure 3.

In operation, the seat B is normally swung to a vertical position by the spring 19 which. causes a downward pull on the rearend of. the arm 18. Downward swinging of. the arm 18 depresses the links 25 causing the crank arms 23 to move downwardly and they hinge pins 22 rotated thru 90 thus swinging their respective trap plates 20 upwardly against upward swinging of thetrap plates 20 forms of invention herein shown and described, without departing from the spirit of the invention or the scope of the following claims. J

I claim:

1. In a closet of the class described, abowl comprising a'rectangular base portion and a top portionincluding a cylindrical body portion providing an internal downwardly facing shoulder about the upper end of the base portion, a seat hinged'to rest upon theupper' edge of said top portion, a fiat trap plate hingedly mounted along one edge beneath the shoulderat each of the side walls of the base portion, means operatively connected between the'seat and said plates for closing the plates acrossthe bowl when the seat is raised and opening the plates against the sidewalls of;

the base when the seat-is lowered, andspring means normally holding the seat in a raised;

position.

2. In a closet of the class described, a bowl comprising abase portion and a body portion mounted upon the; base portion each having of-theseat.

' vROBER'FM. HYDE:

a closure between the bowl sections 5 and 12 and prevents the emission'of odors. When the seat 13 is swung downwardly for use, the

arms 23 whereby the. trap plates 20 swing downwardly against the base side walls 8 toaf 1 links 25 exert an upward pull upon the crank a position beneath the shoulder formed by the restflange 14.,

Opening thru the upper portion of the rear base wall 7 is a vent pipe 35 for venting of odors entrapped in the. base 5 beneath the trap plates 20.

Thus it will be seen that an improved, sanitary dry toilet has been provided which. will effectively overcome the many obj ectional. features of this type of toilet now in general use and wherein no means is provided to prevent the emission of odors into the toilet room. It will also be apparent that a simple con sltruction hasbeen provided whereby the device may be economically: constructed, and one which Wlll be automatic in its operationv for accomplishing the object in view.
